It was pretty nice at the very beginning, when it was still ripping off Hunter x Hunter, but the more it went, the more bloated it became, and now it barely offers anything other than fillers and flashbacks.
|Interesting fantasy ninja setting||Loaded with filler|
|Some cool fights||Extremely slow pace (more than half of episode is filled with flashbacks of previous episodes)|
|Likable characters (except the protagonist, fuck him)||Story resists going anywhere to keep the thing going forever|
|Has some interesting things going in the plot||Just an investment of time no adult can afford anymore|
|Some clever mind games / puzzles characters have to overcome at the start|
